Issue details

When using the Pulumi Cloud ESC UI editor, if one creates structured config using json format such as:

values:
  stuff: [
    {
      foo: "goo",
      moo: "zoo"
    }
  ]

And then save the environment, the value is reformatted to a single line. This makes updates to the values difficult.
